Answer:
881.5 meters.
Step-by-step explanation:
The horizontal plane at the level of wai-kin's eyes divide the height of the cliff into two parts. Let the upper part be represented by x and the lower part be represented by y.
The height of the cliff = x + y
Applying the appropriate trigonometry functions.
To determine the value of x;
Tan θ = 
Tan 
= 
⇒ x = 490 x Tan
= 490 x 0.7265
= 355.985
x = 356 meters
To determine the value of y;
Tan θ =
Tan 
= 
⇒ y = 490 x Tan
= 490 x 1.0724
= 525.476
y = 525.5 meters
Therefore,
The height of the cliff = x + y
= 355.985 + 525.476
= 881.461
The height of the cliff is 881.5 meters.
<span>Given:
family travelled 25 miles in 30 minutes or 50 miles /hr
current time 3.00 pm.
total distance=225 miles.
solution:
speed = distance * time
time = distance/spedd
= 225/50
time = 4.5 hours.
reaching time= 3 hours +4 hour 30 minutes= 7.30 pm</span>
So if you're driving 25 miles per hour, it would take you 7 hours to drive 175 miles.
175 miles ÷ 25 miles = 7 hours.
I honestly don’t understand
Answer:
5 11/85
Step-by-step explanation:
First see how many times a whole number can be found.
436/85 = 5.1294
The denominator goes into the numerator 5 times.
Now we find a new numerator.
436 - (85 * 5) = 11 (this is the amount left over after we made 5 wholes.)
Now we see 5 11/85
It cannot be simplified further.
